## We must configure all utils subdirs since 'make dist' needs the Makefile.
## For those not required for the current set of configure options
## we append '--disable-build' so they can skip tests that would
## fail because, e.g., some libraries were not built.

## Sequentially configure and optionally build all utils subdirs;
## code inspired by automake's way to handle recursive targets.
